|
<p>If you can access the <strong>AutoConnect root path</strong> as http://ESP8266IPADDRESS/_ac from browser, probably the sketch uses <em>ESP8266WebServer::handleClient()</em> without <a href="../api/index.html#handlerequest"><em>AutoConnect::handleRequest()</em></a>.<br />
|
|
For AutoConnect menus to work properly, call <a href="../api/index.html#handlerequest"><em>AutoConnect::handleRequest()</em></a> after <em>ESP8266WebServer::handleClient()</em> invoked, or use <a href="../api/index.html#handleclient"><em>AutoConnect::handleClient()</em></a>. <a href="../api/index.html#handleclient"><em>AutoConnect::handleClient()</em></a> is equivalent <em>ESP8266WebServer::handleClient</em> combinated <a href="../api/index.html#handlerequest"><em>AutoConnect::handleRequest()</em></a>.</p>
|
|
<p>See also the explanation <a href="../basicusage/index.html#esp8266webserver-hosted-or-parasitic">here</a>.</p>

|
|
<p>Captive portal detection could not be trapped. It is necessary to disconnect and reset ESP8266 to clear memorized connection data in ESP8266. Also, It may be displayed on the smartphone if the connection information of esp8266ap is wrong. In that case, delete the connection information of esp8266ap memorized by the smartphone once.</p>

|
|
<p>Maybe it is successfully connected at the <strong>first WiFi.begin</strong>. ESP8266 remembers the last SSID successfully connected and will use at the next. It means SoftAP will only start up when the first <em>WiFi.begin()</em> fails.</p>
|
|
<p>The saved SSID would be cleared by <em>WiFi.disconnect()</em> with WIFI_STA mode. If you do not want automatic reconnection, you can erase the memorized SSID with the following simple sketch.</p>

<p>If ESP8266 hang up after reset by AutoConnect menu, perhaps manual reset is not yet. Especially if it is not manual reset yet after uploading the sketch, the boot mode will stay 'Uart Download'. There is some discussion about this on the Github's ESP8266 core: <a href="https://github.com/esp8266/Arduino/issues/1017">https://github.com/esp8266/Arduino/issues/1017</a></p>

<p>If you received the following message, the boot mode is still sketch uploaded. It needs to the manual reset once.</p>

<p>Make some sketches for erasing the EEPROM area, or some erasing utility is needed. You can prepare the sketch to erase the saved credential with <em>AutoConnectCredential</em>.

<p>It increases about 53K bytes compared to the case without AutoConnect. A sketch size of the most simple example introduced in the Getting started is about 330K bytes. (270K byte without AutoConnect)</p>

<p>Because AutoConnect does not send a login success response to the captive portal requests from the smartphone. The login success response varies iOS, Android and Windows. By analyzing the request URL of different login success inquiries for each OS, the correct behavior can be implemented, but not yet. Please resets ESP8266 from the AutoConnect menu.</p>
